Votre véhicule est équipé de COUSSINS GONFLABLES INTELLI-
GENTS conçus selon les normes de sécurité américaines applicables
aux véhicules à moteur (FMVSS208). Le boîtier électronique (ECU)
des coussins gonflables régule le déploiement de ces derniers sur la
base des informations qu’il reçoit des capteurs, etc., indiqués ci-des-
sus dans le schéma illustrant les composants du système. Parmi ces
informations figurent la gravité du c hoc et les informations de l’occu-
pant. Le déploiement rapide des coussins gonflables est obtenu au
moyen d’une réaction chimique dan s les dispositifs pyrotechniques,
qui produit un gaz inoffensif permet tant d’amortir le mouvement des
occupants. Capteurs d’impact avant
